Nobelium
It comes after Molybdenum
Element 102
It's actually older than you
It's atomic mass is 259
It is the only one of it's kind
Dangerously unstable
That seems to be its' main label
It causes it to decay
Makes you wonder: "Why won't it stay?"
Highly radioactive
Which makes it really unattractive
Don't get to close
or you could die
It'll kill you right there
before your eyes
It's totally useless
Created by humans
Rare element found on earth
We think an accident caused its birth
Only lives 51 seconds
Makes scientists ask many questions
But for now they'll leave it alone
Forever alone in its own little zone
